Aideepen | ST25DV16K RFID Dynamic Tag Frequency Module with I2C NFC Dual Interface 16Kbit EEPROM Wireless Configuration for IoT Devices

Features:1. This RFID tag supports both I2C and NFC interfaces for flexible data interaction.2. Compliant with ISO/IEC 15693 standard, enabling wireless reading and identification by mainstream smartphones.3. Features 16Kbit EEPROM storage for data logging and configuration storage.4. Can function as an “I2C to RFID” transmission system to wirelessly send and receive data from mobile devices.5. Plug-and-play design with STEMMA QT interface for rapid integration and development.Product Description:This RFID tag interacts with smartphones similarly to other RFID tags but can be reprogrammed via I2C. It appears as an ISO/IEC 15693-compliant (13.56MHz) chip readable by smartphones and tablets. Note: Popular RFID reader/writer chips like the PN532 do not support the ISO15693 standard. Therefore, once programmed, ST25DV tags cannot be read using these chips! This product can function as an “I2C to RFID” transmission system to wirelessly send and receive data from mobile devices (though you will need to develop a custom application for such projects).Key Specifications:Storage Capacity: 16Kbit (2KB) EEPROMCommunication Interfaces:RF: ISO 15693 / NFC Forum Type 5I2C: Standard I2C slave devicePower Supply: 3.3V (I2C operation) / RF field energy harvesting (optional)Interface: STEMMA QT / Qwiic (configurable I2C address)Module Dimensions: 31.8mm x 25.5mm x 5mmCore Features:16Kbit NFC Type 5 tag (dynamically readable/writable)Dual interfaces: I2C + RF (13.56MHz NFC)Energy Harvesting Capability (Optional)STEMMA QT/Qwiic Interface, Plug-and-Play, No Soldering RequiredHigh Security: 4 Independent Password ZonesOpen-Source Ecosystem: Drivers Available for Mainstream Open-Source Development EnvironmentsPrimary Applications:Wireless Configuration for IoT DevicesAsset Tracking and ManagementSmart Packaging and Product AuthenticationPassive Sensor Data LoggingPackage ContentsST25DV16K Module x16-Pin Header x1
